FOUNTAIN PEN.

Application filed October 21, 1925, Serial No. 63,865, and in GreatBritain November &, 1924.

This invention has relation to improvements in self-filling fountainpens of the kind having a rubber ink-containing sac.

With pens of this kind, those not skilled in the art find di'fficulty inremoving the pen point when required, as'for example, for adjustment ofthe feed bar or to replace the pen point, as is necessary when cheap penpoints are used and the pen points become Worn or corroded. Such personsoften employ tools such as pliers whereby they spoil the pen point andpossibly also the feed bar without succeeding in removing them. i

It is an object of the present invention to provide a construction bywhich the pen point may be readily replaced or the feed bar and the penpoint more easily removed.

According to the present invention a fountain pen of the kind describedhas a point section formed in two parts, one part having theink-containing sac attached, and being mounted in the open end of thebarrel, and the other part carrying the pen point and feed bar and beingmounted in the outer end of the first mentioned part as by screwing orfrictionally.

One form of the present invention will now be described with referenceto the accompanying drawings, wherein Fig. 1 shows a fountain pen partlyin section, and

Fig. 2 shows the pen with the cap removed and the point section partsseparated.

l is the barrel of usual form. The point section is formed in two parts,one part 2 to which the ink-containing sac 3 is attached, being heldfrictionally in the open end of the barrel 1 in the usual way; thesecond part 4.- of the point section is threaded atvits end 5 andscrewed into the internally threaded end of the part 2. 6 is the feedbar and 7 the pen point, both of which are mounted frietionally in thepart 4 in the usual way.

Thus, if it be desired to replace the pen point a new threaded part 4carrying a new pen point and feed bar may be readily mounted in place;or, if it be desired to remove the feed bar for adjustment, it maybepressed out from the inner end of the part 4 and thusloosened, wherebythe pen point and feed bar may be readily removed.

What I claim is 2-- l. 'A fountain pen of the kind described I tionedpart so that the feed bar extends into'.

the open end of said first mentioned part. 2. A fountain pen of the kinddescribed having a point section of bi-partite constructure, one part oftubular form with open ends having the ink-containing sac attached andbeing frictionally mounted in the open end of the barrel, and the otherpart of tubular form with open ends carrying the pen point and the feedbar and being removably mounted in the outer end of the first mentionedpart so that the feed bar extends into the open end of said firstmentioned part.

3. A fountain pen of the kind described having a point section of.bi-partite construction, one part of tubular form with open ends havingthe ink-containing sac attached and being frictionally mounted in theopen end of the barrel, and the other part of tubular form with openends carrying the pen point and the feed bar and belng screwed into theouter end of the first mentioned part so'that the feed bar extends intothe open end of said first mentioned part.

Dated this 7th day of October 1925.
